The Geneva International Motor Show was an annual auto show held in March in the Swiss city of Geneva. The show was hosted at the Palexpo, a convention centre located next to the Geneva Cointrin International Airport. The Salon was organised by the Organisation Internationale des Constructeurs d'Automobiles, and was considered an important major international auto show. First held in 1905, the Salon hosted almost all major internal combustion engined models in the history of the automobile, along with benzene- and steam-powered cars from the beginning of the century.
